Powder wettability measurement with the Washburn method. In its most general form the Lucas Washburn equation describes the penetration length ( L {\displaystyle L} ) of a liquid into a capillary pore or tube with time t {\displaystyle t} as L = ( D t ) 1 2 {\displaystyle L=(Dt)^{\frac {1}{2}}} , where D {\displaystyle D} is a simplified ...
A force balance equation known as Washburn's equation for the above material having cylindrical pores is given as: [1] ...
Assisted by his graduate student A.L. Washburn, Cannon set out to test whether stomach contractions were responsible for signaling hunger to the brain. Arthur Lawrence Washburn (1887-1965) was a graduate student at Harvard Medical School when he participated in the hunger experiment. Washburn had entered Harvard College in 1906 and graduated ...

The recommendation for anyone taking a tirzepatide and an oral birth control pill is to use a backup barrier method like a condom for the first four weeks and then for four weeks after each dose ...
Cloth, treated to be hydrophobic, shows a high contact angle. The theoretical description of contact angle arises from the consideration of a thermodynamic equilibrium between the three phases: the liquid phase (L), the solid phase (S), and the gas or vapor phase (G) (which could be a mixture of ambient atmosphere and an equilibrium concentration of the liquid vapor).
When Hiram died, Washburn purchased a cat in a New York City pet shop. That cat was angry and territorial, so much so that Washburn closed off more than one room in her house for the cat's sole use. [7] In 1921, Washburn gave her APA presidential address in which she discussed the importance of introspection as a legitimate method of inquisition.
